Well, it seems the provided context was more interested in showing off its website navigation than in spilling any actual secrets about sofa durability. Fear not, for I can answer this without its help.
Asking how long a leather sofa should last is a bit like asking how long a car will run; it really depends on the model and how you treat it. A top-of-the-line, full-grain leather sofa built on a solid hardwood frame can be a true lifer, sticking around for 25 years or even longer. It might just outlast your mortgage, becoming a distinguished family heirloom that has seen more movie nights than a cinema usher.
On the other end of the spectrum, a sofa made from cheaper "bonded leather" might give you a good five years before it starts to peel and look like it's suffering from a bad sunburn. This type of material is essentially the fast fashion of the furniture world—looks good for a season, but isn't built for a long-term commitment.
Ultimately, a leather sofa's lifespan comes down to the quality of the leather, the sturdiness of its frame and suspension, and the level of care it receives. If you treat it with regular cleaning and conditioning and protect it from its mortal enemy, direct sunlight, you're investing in a long-term relationship. If you let the dog use it as a launching pad and the kids treat it like a coloring book, its golden years will be cut tragically short.
